VIOLIN-BRID GE.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed October 6, 1914. Serial No. 865,225.

I b all whom it may concern Be it known that I, LOUIS LUMriniE, a citizen of the French Republic, residing at 262 Cours Gambctta, Lyon, France, have invented new and useful Improvements in Violin-Bridges, of which the following is a specification.

We know already violin-bridges one foot of which exercises a pressure on the front or belly of the instrument, whereas the other foot exercises its pressure on the back, but the arrangements used do not allow of distributing the pressure properly on each of the two boards, and besides they require a hole to be made in the top-board, which disturbs its vibrations more or less. The bridge which is the object of this invention is constructed so that while both feet always rest on the belly, it possesses a third foot which penetrates inside the instrument through one of the existing f-holes and rests on the back. The annexed drawing shows as an example the application of this arrangement to a Violoncello.

Figure 1 represents the cross-section of the instrument at the bridge. Fig. 2 shows a different manner of executing the system.

Bridge A Fig. 1 rests with its two feet 1 and 2 on the belly 3; to one of these feet (2) there is rigidly fixed a bent metal leg 6 (preferably made of hardened steel) which passes through f-holes 5, without touching the belly, and its end or foot 8, which may be pointed, rests on the back 12. Leg 6 is fixed to the bridge 4 by means of bolts or screws 7, 7 which once screwed down, hold the two pieces tight together. This leg rests on the back 12 which is supplied with a peg 9 to receive the point of the leg. This arrangement makes it possible to distribute the pressure of the strings at will between the front and back, by regulating, according to the result to be obtained, the vertical distance of the contact-points 2 and 8. Such regulating may be obtained either by the construction or by an assemblage that can be regulated as shown in Fig. 2 which allows of varying (according to the requirements) the relative pressures on the instrument completely put together. For this purpose the joining of leg 6 Fig. 2 with the bridge takes place by means of a horizontal bracket 10 fixed rigidly on leg 6 by means of two nuts 11, 11 which once screwed on the screw-part of this leg 6 form a rigid connection. It will be understood that by screwing the nuts in the way required, one

can, by lifting up foot 2, reduce the pressure it exercises on the belly and even raise it completely out of contact with the belly and so transmit the pressure of foot 2 wholly or in part to the back through leg 6. One can. therefore distribute this pressure according to ones requirements.

hat I claim as my invention and desire to secure by Letters Patent of the United States is:

1. A violin bridge provided with two feet adapted to bear on the belly of the instrument and a supplemental leg and foot adapted to be inserted into the body of the instrument through one of the f-holes and to bear on the back of the instrument.

2. A violin bridge provided with two feet adapted to bear on the belly of the instru ment and .a supplemental leg and foot adapted to be inserted into the body of the instrument through one of the f-holes and to bear on the back of the instrument and means for adjusting the length of the supplemental leg.

3. A violin bridge provided with two feet adapted to bear on the belly of the instrument, a bracket rigidly attached to said bridge, and a supplen'iental leg adjustably connected to said bracket and adapted to be inserted into the body of the instrument through one of the f-holes and to bear on the back of the instrument.

In testimony whereof I have signed name to this specification in the presence of two subscribing witnesses.

LOUIS LUMIERE.
